Section 1: Introduction

Section 2: Overall Description

2.1 Product Perspective

This product is independent and totally self-contained. Although a Raspberry Pi is used to track people movement, it is considered a part of this system.

2.1.1 System Interfaces

Raspberry Pi motion capture that tracks people. Uses Python post method to communicate with web-server (Node).
HTTP web server. Accesses database to modify and retrieve data.

2.1.2 User interfaces

Website is only user interface, but it is divided into three privilege levels: each with access to successively greater features. Customer: Home page Reservation page
Orders/Menu page
Login Portal

Employee:
Enhanced Reservation page
Enhanced Orders/Menu

Manager/Owner:
